Listening and Speaking introduces the topic of “ask about online habits”. Many middle school students have been surfing the Internet for many years, but what they do with the Internet and how much time they spend every day may not be very clear to themselves, nor to other students. This section allows students to investigate their peers' Internet use, which is conducive to their mutual understanding and understanding of the Internet. It can also help them reflect on their own online behavior, learn from other people's good online habits, and get rid of their bad online behavior.The listening text of this section is an investigation interview. The investigators interview specific groups with the same questions to obtain information, so as to understand their views, practices or attitudes on this issue.

The answers of the three respondents provide rich and different information, and achieve the purpose of the investigators. The oral discourse structure of survey interviews generally includes greeting and explaining the purpose of the interview, presenting the interview questions and the respondents' answers. Listening and Talking introduces the theme of “choosing the right application ". Listening text is a conversation between Laura and Xiao Bo.

人教版高中政治必修1第一課神奇的貨幣教案
1、外匯與外幣的關(guān)系：（1）外匯包括外幣，但外匯不等于就是外幣。外幣是指外國的貨幣，包括外國的紙幣、鑄幣；外匯通常是以外國貨幣表示的用于國際間結(jié)算的支付手段，具體包括外幣、外幣有價證券、外幣支付憑證等。（2）外幣屬于外匯的范圍，但不能把二者等同起來。通常情況下，只有可以自由兌換的外幣才是外匯，因?yàn)橥鈪R的實(shí)質(zhì)是國際支付手段，如果某種貨幣不能自由兌換，它就不能成為國際支付手段。外匯執(zhí)行的 主要是貨幣的支付手段的職能。（3）持有外匯意味著對外匯發(fā)行國擁有債權(quán)。持有外匯過多，一方面意味著國際支付能力強(qiáng)和有可能對外匯發(fā)行國施加影響；另一方面則意味著大量該由本國享受的資源，被借給外國利用，并要承擔(dān)外匯貶值的風(fēng)險。2、關(guān)于幣值變化的分析：（1）對貨幣升值的具體分析：一個國家的貨幣升值（上浮）后，同量的這種貨幣能比以前換 取更多的他國貨幣，買到更多的他國商品。

下面是對以高技術(shù)產(chǎn)業(yè)為主的新工業(yè)區(qū)的內(nèi)容進(jìn)行講解，教材以美國“硅谷”為例，首先談的是高技術(shù)工業(yè)的特點(diǎn)，然后講述的是“硅谷”的發(fā)展條件，由于教學(xué)模式與意大利新工業(yè)區(qū)的內(nèi)容基本一致，這里就不再贅述了。接下來教材中提到的與之對照的案例同樣是以高技術(shù)產(chǎn)業(yè)而聞名的中關(guān)村，由于中關(guān)村在國內(nèi)的知名度較高，一般學(xué)生都有所了解，因此不妨讓學(xué)生談?wù)勛约旱目捶ǎ簩τ诟咝录夹g(shù)產(chǎn)業(yè)的發(fā)展有何建議，相對于發(fā)展較為成功的“硅谷”我們需要學(xué)習(xí)的方面又是哪些？案例中最后一個問題很值得深省，我國的新工業(yè)區(qū)到底怎樣做才能夠獲得成功，簡單的模仿下我們?nèi)鄙俚挠质鞘裁?？這個問題可以作為拓展，讓學(xué)生寫一篇簡短的論文作為課后作業(yè)。最后做以簡單的課堂小結(jié)。本節(jié)內(nèi)容的教學(xué)可能會相對繁雜，而案例之間的分析過程又過于雷同，所以難免枯燥。在處理這個問題上，我將盡量做到詳略得當(dāng)，主要培養(yǎng)學(xué)生的自主學(xué)習(xí)能力。

人教版高中地理必修1第二章第三節(jié)常見的天氣系統(tǒng)說課稿
一、說教材（一）教材的地位與作用本節(jié)內(nèi)容是本單元知識結(jié)構(gòu)中重要的一環(huán)，具有承上啟下的作用。由于各種天氣現(xiàn)象的產(chǎn)生與大氣的熱力狀況、大氣的運(yùn)動有密切的聯(lián)系，所以，本課是在綜合前兩節(jié)內(nèi)容的基礎(chǔ)上，闡述常見的天氣現(xiàn)象的成因。在實(shí)際生活中，天氣系統(tǒng)與人們的生產(chǎn)、生活密切相關(guān)。本課所講的內(nèi)容對于學(xué)生了解天氣變化的最基本因素，普及天氣預(yù)報知識具有積極的意義。（二）教學(xué)目標(biāo)(1)知識與技能目標(biāo)：⑴從圖片和簡易圖中，知道氣團(tuán)（冷氣團(tuán)、暖氣團(tuán)）的概念；鋒的概念與分類；低壓（氣旋）、高壓（反氣旋）、高壓脊、低壓槽的概念。 ⑵從氣溫、氣壓、濕度、降水、風(fēng)等幾方面分析各種天氣系統(tǒng)的形成及其氣流特點(diǎn)，并綜合出各種天氣系統(tǒng)控制下的天氣狀況。⑶知道低壓槽和高壓脊概念及在圖上的表示方法。(2)過程與方法目標(biāo)：⑴讓學(xué)生能閱讀和簡單分析天氣圖，解釋天氣變化現(xiàn)象；⑵用案例說明氣象災(zāi)害發(fā)生的原因和危害；
人教版高中歷史必修1新中國的民主政治建設(shè)說課稿2篇
（一）教材的地位新中國的成立是20世紀(jì)的一件大事。它結(jié)束了幾千年封建專制統(tǒng)治的歷史，開啟了中華民族發(fā)展的新紀(jì)元。本課側(cè)重這一時期一個非常顯著的特征，即制度的更新，它本身具有知識的延續(xù)性和鋪墊性。新中國的成立促進(jìn)了社會經(jīng)濟(jì)的發(fā)展，也為祖國的統(tǒng)一奠定了重要基礎(chǔ)。（二）教學(xué)目標(biāo)依據(jù)新課程以人為本，促進(jìn)學(xué)生全面發(fā)展的要求，同時,針對高一年級學(xué)生具備一定基礎(chǔ)知識但掌握不牢固，對歷史興趣濃厚但又自制能力差的特點(diǎn)，我對本課的三維目標(biāo)設(shè)定如下：見多媒體。（三）教學(xué)重點(diǎn)的確定及處理本課的主題是新中國的民主政治建設(shè)，這個問題的掌握對以后學(xué)習(xí)中國民主政治建設(shè)的進(jìn)程有很大幫助，并且學(xué)生能力的提高也有賴于對它的認(rèn)識，所以確定“人民代表大會制度的創(chuàng)立”是教學(xué)重點(diǎn)。
人教版高中生物必修1生命活動的主要承擔(dān)者—蛋白質(zhì)說課稿
第五，蛋白質(zhì)的功能。蛋白質(zhì)功能具有多樣性，由學(xué)生對照教材，進(jìn)行總結(jié)。為什么蛋白質(zhì)有那么多功能呢？根據(jù)我們學(xué)習(xí)生物學(xué)的經(jīng)驗(yàn)可知道：生物的結(jié)構(gòu)決定功能。再要求剛才的那四個同學(xué)上臺組合多肽鏈。以不同位置組合，就會形成很多種多肽鏈，進(jìn)而形成很多種蛋白質(zhì)。每一種蛋白質(zhì)都有其特定的功能，所以蛋白質(zhì)具有多樣性，其功能也具有多樣性。第六，總結(jié)。蛋白質(zhì)是細(xì)胞和生物體中重要的有機(jī)化合物，是一切生命活動的主要承擔(dān)者。蛋白質(zhì)的多樣性是形形色色生物和絢麗多彩生命活動的物質(zhì)基礎(chǔ)。（可以由學(xué)生總結(jié)）第七，教學(xué)評價。由于只有一節(jié)課時間，課堂上對重點(diǎn)、難點(diǎn)知識的解析還不能做到舉一反三的深度，因此盡管學(xué)生課堂反應(yīng)熱烈，對知識點(diǎn)的接受程度也達(dá)到了預(yù)期的要求，但在做課后練習(xí)時，也會出現(xiàn)一些問題。所以傳統(tǒng)的講練結(jié)合還是要結(jié)合起來運(yùn)用才能取得更好的效果。為此本節(jié)內(nèi)容需要2課時來完成。
人教版高中政治必修1按勞分配為主體-多種分配方式并存說課稿
4、課堂討論：社會主義的根本原則是共同富裕，這也是正確處理分配關(guān)系的目標(biāo)。而十五大報告卻進(jìn)一步明確指出“允許和鼓勵一部分人通過誠實(shí)勞動和合法經(jīng)營先富起來，允許和鼓勵資本、技術(shù)等生產(chǎn)要素參與收益分配”。這矛盾嗎？為什么？以小組方式進(jìn)行討論，再以代表的形式發(fā)表意見，這樣既調(diào)動了學(xué)生的積極性，也使學(xué)生對內(nèi)容有了更深層次的了解。最后老師加以總結(jié)，用“蛋糕效應(yīng)”來闡述“效率優(yōu)先，兼顧公平”的關(guān)系，既形象又貼切，加深學(xué)生的理解。本課時內(nèi)容比較抽象，學(xué)生對于概念的理解有較大的難度。因此在教學(xué)中我采用多媒體課件教學(xué)，聯(lián)系生活實(shí)際，讓學(xué)生在生活中去體會貨幣的職責(zé)，區(qū)分貨幣的職能，以便達(dá)到學(xué)以致用的目的。同時適時設(shè)置疑問，讓學(xué)生與我共同思考，真正實(shí)現(xiàn)“師生互動，生生互動”，調(diào)動學(xué)生積極，主動的參與到教學(xué)實(shí)踐活動中。（三）課堂小結(jié)，強(qiáng)化認(rèn)識。（2—3分鐘）通過歸納小結(jié)，既強(qiáng)調(diào)了重點(diǎn)，又鞏固了本節(jié)知識，幫助學(xué)生形成知識網(wǎng)絡(luò)，便于課后理解記憶。
人教版高中歷史必修1古代希臘民主政治說課稿
（4）評價民主通過對雅典公民享有充分的言論自由的介紹及展示伯利克里的講話、陶片放逐法，使學(xué)生認(rèn)識到，雅典的民主在統(tǒng)治階級內(nèi)部已經(jīng)達(dá)到了非常高的層次，并促進(jìn)了希臘人完整人格的形成。通過伯利克里講話、圖片、文字分別講述希臘人重責(zé)任感、渴求知識的民族性格，并請學(xué)生朗讀有關(guān)雅典人生活的有關(guān)文字，讓學(xué)生在閱讀中感情逐漸升溫，引發(fā)學(xué)生對民主的充分認(rèn)同及對雅典人重精神生活的無限神往。問題設(shè)置：讓學(xué)生思考雅典民主政治對后世西方政治制度的重大影響。同時指出“民主是不可抗拒的歷史潮流！”讓學(xué)生在原有知識的基礎(chǔ)上認(rèn)識民主政治的必然性。用書中的兩段材料分析希臘民主政治的特征和實(shí)質(zhì)，分析其影響。4.課堂小結(jié)對本課內(nèi)容進(jìn)行概括性的總結(jié)5.知能訓(xùn)練，運(yùn)用遷移體現(xiàn)一定的層次性，滿足不同層次學(xué)生的要求。6.布置作業(yè)撰寫歷史論文首先布置論文范圍、主題；其次進(jìn)行舉例；最后提供相關(guān)查閱資料的網(wǎng)址。
人教版高中政治必修2本質(zhì)是人民當(dāng)家做主說課稿
環(huán)節(jié)三案例分析突出難點(diǎn)這一環(huán)節(jié)，我將用多媒體展示我國反腐行動，將一個個貪污腐敗者給予法律制裁的案例和東突分子分裂活動的例子，來得出我國專政的職能。這些例子具有典型性和時效性，能讓學(xué)生容易從例子中得出知識點(diǎn)，引導(dǎo)學(xué)生理解我國的專政是對極少數(shù)敵人實(shí)行的專政。并通過《反分裂法》的制定，讓學(xué)生討論為什么我國既要實(shí)行民主職能又實(shí)行專政職能，以此來分析民主與專政的關(guān)系（區(qū)別和聯(lián)系）。培養(yǎng)學(xué)生獲取信息的能力，自主學(xué)習(xí)的能力以及全面看問題的能力，再結(jié)合教師的講授，給學(xué)生一種茅塞頓開的感覺。環(huán)節(jié)四 情景回歸 情感升華這一環(huán)節(jié)，我將設(shè)置分組討論，讓學(xué)生們分別從人民民主專政的重要地位、“民主”與“專政”這兩項職能、改革開放的歷史條件下新時期內(nèi)容三個方面來分析為什么堅持人民民主是正義的事，討論后每組派出代表來發(fā)表各自組的結(jié)論，得出我國要堅持人民民主專政。通過小組討論，使學(xué)生學(xué)會在合作中學(xué)習(xí)，提高學(xué)生的語言表達(dá)和思維能力。
